Abstract

Purpose

The purpose of this paper is to gain a better understanding of the market timing skills displayed by hedge fund managers during the 2007‐08 financial crisis.

Design/methodology/approach

The performance of a market timer can be measured through the 1966 Treynor and Mazuy model, provided the regression alpha is properly adjusted by using the cost of an option‐based replicating portfolio, as shown by Hübner. The paper adapts this approach to the case of multi‐factor models with positive, negative or neutral betas. This new approach is applied on a sample of hedge funds whose managers are likely to exhibit market timing skills. This concentrates on funds that post weekly returns, and analyzes three hedge funds strategies in particular: long‐short equity, managed futures, and funds of hedge funds. The paper analyzes a particular period during which the managers of these funds are likely to magnify their presumed skills, namely around the financial and banking crisis of 2008.

Findings

Some funds adopt a positive convexity as a response to the US market index, while others have a concave sensitivity to the returns of an emerging market index. Thus, the paper identifies “positive”, “mixed” and “negative” market timers. A number of signs indicate that only positive market timers manage to acquire options below their cost, and deliver economic significant performance, even in the midst of the financial crisis. Negative market timers, by contrast, behave as if they were forced to sell options without getting the associated premium. This behaviour is interpreted as a possible result of re sales, leading them to liquidate positions under the pressure of redemption orders, and inducing negative performance adjusted for market timing.

Originality/value

The paper suggests that the convexity in returns that is generally associated with market timing can be attributed to three sources: timing skills, exposure to nonlinear risk factors, or liquidity pressures. It manages to identify the impact of the latter two effects in the context of hedge funds.

Abstract

Purpose

The purpose of this paper is to examine the effect of institutional investors’ ownership and type on information asymmetry and stock market liquidity in France.

Design/methodology/approach

The sample includes 162 French-listed firms from 2007 to 2009. The methodology relies on linear regressions using the method of ordinary least square. Before examining the interaction between liquidity and institutional investors, the authors check for the existence of the endogeneity problem by applying the Durbin-Wu-Hausman test of Davidson and MacKinnon (1993). The results of the endogeneity test show that institutional investors’ ownership and stock liquidity are endogenous. A simultaneous equation model using the double least square method is then tested to address this problem.

Findings

The findings show that the proportion of institutional investors has a positive and significant effect on stock-market liquidity, which confirms the signal theory and trading hypothesis. These investors perform high trading activity which favorably affects market liquidity. The results also show that pension funds improve stock liquidity. This result suggests that pension funds manage huge assets decreasing transaction costs and improving liquidity. They display a positive signal to the market about more transparency and a low level of informational asymmetry.

Practical implications

These results highlight the institutional investors’ role in defining the level of liquidity on the French market. The findings also stress the relevance of developing institutional investors’ demand for the Paris market in order to better assess firm value, protect minority ownership and improve market liquidity.

Originality/value

In the French institutional setting, institutional investors act as a control device since minority shareholder interests are less protected than in Anglo-American counterparts. This result highlights the significant role of institutional investors in corporate governance structures and on financial markets. Their presence is a guarantee for minority interest protection and for more liquid stocks.
